The pricing for Gray Resin is based on model volume, which is the volume of your model used to calculate the material cost (mm³).
Additionally, a startup cost is applied to the price of your model. This is a fixed cost independent from the parameters of your model. If you order two or more copies of a model, the price automatically decreases because the preparation of multiple copies can be carried out more efficiently.
Gray resin is suitable for visual models with limited functionality, but with a high level of detail. Applications range from visual models to model trains and figurines.
Stereolithography is used to build your design with this material. Starting from a 3D model, a model is built by cutting the file into thin layers with specialized software. A support structure is created, where needed, in order to deal with overhangs and cavities.
The process takes place in a large tank and begins when a layer of liquid polymer is spread over a platform. This machine then uses a computer-controlled laser to draw the first layer onto the surface of a liquid polymer, which hardens where struck by the laser. The model is then lowered and the next layer is then drawn directly on top of the previous one. This is repeated until the model is finished. In this way, layer by layer, an object is “drawn” in the liquid by the beam, with the layers being consolidated throughout the process.
When the object is complete, it is raised out of the tank with the supporting platform – much like a submarine rising to the surface of the water – with the excess liquid flowing away. The supports are removed manually after the model is taken from the machine.
- The visibility of the layers strongly depends on the shape or the design of the model. For instance, on a curved surface, layers will be much more visible
- Some sides of your gray resin model (depending on the print orientation) will be matte and contain small dots where 3D printing support structures were touching the model. These support marks are sandpapered as much as possible, however, sandpapering the model introduces scratches
- Resins will discolor more because of direct UV light than any other material. To slow down discoloration, we recommend varnishing or painting your model
Learning about our materials is one thing, seeing and touching them another. That's why we've designed sample kits based on our Periodic Table of Materials.
Resin Sample Kit
Includes a sample of High Detail Resin, Standard Resin, Mammoth Resin and Gray Resin.
We want you to have access to as many 3D printing materials as possible, so you can make the best choice for your project. If you didn’t really find what you were looking for on i.materialise, you might want to take a look at Materialise OnSite. OnSite is our other online platform, mainly used by professionals who need rapid prototyping and manufacturing in an industrial environment.
This means you can additionally find these materials on OnSite:
- Poly1500 : A translucent material with properties comparable to those of PP (polypropylene) and engineering plastics. Being impact-resistant and durable, this material is suited for rigid, functional prototypes in a large range of applications. This material can also be ordered through OnSite's NextDay service, which means your parts will be shipped the same day.
- TuskXC2700W : A white material that is suitable for strong, water-resistant prototypes with ABS- and PBT-like specifications (e.g. parts for water flow analysis and wind tunnel testing). This material can also be ordered through OnSite's NextDay service, which means your parts will be shipped the same day.
